The Golden Apple is an apple in Super Paper Mario that only appears once in the game. In The Overthere, after going through Door E, Mario, Luigi and Bowser will find Princess Peach fast asleep after she ate the apple.
Luvbi explained that the Golden Apple is so delectable that anyone who eats it will end up falling into deep sleep for 100 years. She also says that there's a taboo fruit around that may restore her consciousness. The fruit that Mario and the gang must get is a Black Apple, the only fruit that wakes up Peach. (All other fruits transform her in humorous ways, such as making her giant or changing her into an actual peach.) The Yellow Apple is similar in appearance to the Golden Apple.
Notes
- The Golden Apple may be a reference to the "forbidden fruit" of the Garden of Eden, which was also an apple. Golden apples were also present in Greek mythology, which is another source of Chapter 7's material.
